    Abstract
    Controversy is a complex concept that has been attracting attention of scholars from diverse fields. In the era of Internet and social media, detecting controversy and controversial concepts by the means of automatic methods is especially important. Web searchers could be alerted when the contents they consume are controversial or when they attempt to acquire information on disputed topics. Presenting users with the indications and explanations of the controversy should offer them chance to see the "wider picture" rather than letting them obtain one-sided views. In this work we first introduce a formal model of controversy as the basis of computational approaches to detecting controversial concepts. Then we propose a classification based method for automatic detection of controversial articles and categories in Wikipedia. Next, we demonstrate how to use the obtained results for the estimation of the controversy level of search queries. The proposed method can be incorporated into search engines as a component responsible for detection of queries related to controversial topics. The method is independent of the search engine's retrieval and search results recommendation algorithms, and is therefore unaffected by a possible filter bubble. Our approach can be also applied in Wikipedia or other knowledge bases for supporting the detection of controversy and content maintenance. Finally, we believe that our results could be useful for social science researchers for understanding the complex nature of controversy and in fostering their studies.

    Rez. in: JASIST 55(2004) no.7, S.651-652 (D.G. Smith): "A complex myriad of online information sources and services are currently accessible to knowledge workers worldwide. Those who have a computer equipped with a modern or Internet access can avail themselves of bibliographic, scientific, and full-text databases in a staggering number of disciplines. These online services, fueled by technological advancement, are in a constant state of change. Innovation occurs so quickly that it is difficult for knowledge workers to remember any other technological reality but the present. In such an environment, the origin of online information services often goes unconsidered. A History of Online Information Services, 1963-1976, by Charles P. Bourne and Trudi Bellardo Hahn, sheds light an the pioneering efforts of those who made current online information services possible. Michael Buckland states in the book's foreword that Bourne and Hahn's volume is the first history of the early online years. It covers the appearance of the first online information retrieval system in 1963 and concludes during 1976 when several commercial online information services, including DIALOG and LEXIS, became forerunners in the nascent online industry. Although developments in computing technology and communication networks were important to early online efforts, these topics are not discussed in the book. However, there are cases when offline computing technologies, such as database searching with punched cards, are reviewed if they are important to the development of online retrieval systems. ...
    Overall, Bourne and Hahn's book is richly detailed and extensively documented. In the book's introduction, the authors provide a good overview of other online system histories, but they also write about a lack of archival and secondary sources in this area. This explains why it took the authors 15 years to gather information for this volume, most of it derived from technical reports, newsletters, and personal interviews. From a research standpoint, the authors have done an excellent job. However, while no one can take issue with the book's level of scholarship, the presentation of the research could have been more effective. The majority of the book is written in a straightforward, factual manner that is difficult to read as an historical narrative. Except for Chapter 10, there is very little writing in the book that engages the reader and captures the human side of the online information retrieval story. A quote from W. Boyd Rayward an the back of the book's dust cover calls the work "encyclopedic," and in many ways the book as it exists would have worked better as an encyclopedia. Even the book's layout, with double instead of single columns, hints at its reference-like qualities. To be fair, though, it is entirely possible that Bourse and Hahn may have wanted to create a book with a human interest angle, but the lack of documentation may have prevented them from creating such a work. In short, A History of Online Information Services, 1963-1976, does a commendable job of encapsulating the significant people, organizations, and events that helped shape early online information services. Given the problems Bourne and Hahn had in gathering historical evidence for their book, it makes one wonder about the implications for future historical work in the online field. One can only hope that organizations are archiving enough historical material to be able to write the post-1976 online story."

    Abstract
    Universitätsbibliotheken, Archive und Museen müssen adäquate Strategien der Erschließung, des Zugangs und der Archivierung für elektronische Publikationen anbieten. Dabei mangelt es an standardisierten Lösungen und nutzerorientierten Herangehensweisen. Ein Konzept, welches XML als Basis für ein "portal computing" nutzt, kann als Ausgangspunkt dienen, um die Probleme unter bibliothekarischen, dokumentarischen und rechentechnischen Gesichtspunkten lösen zu können. Das Beispiel "Dissertationsportale" zeigt eine Möglichkeit, verteilte und unterschiedlich strukturierte Dokumente mit multimedialen Bestandteilen über ein einheitliches Portal zu verwalten und recherchierbar zu machen

    Abstract
    Reviews the PowerSearch multifile searching software introduced by ORBIT Search Service as it is used for searching patent databases. Looks at its useful features: deduping, patent family grouping, merge, and virtual file merging. Looks at some possible improvements to both PowerSearch itself and to the ORBIT system to accomodate PowerSearch

    Abstract
    Hundreds of scholarly studies have investigated various aspects of Wikipedia. Although a number of literature reviews have provided overviews of this vast body of research, none has specifically focused on the readers of Wikipedia and issues concerning its readership. In this systematic literature review, we review 99 studies to synthesize current knowledge regarding the readership of Wikipedia and provide an analysis of research methods employed. The scholarly research has found that Wikipedia is popular not only for lighter topics such as entertainment but also for more serious topics such as health and legal information. Scholars, librarians, and students are common users, and Wikipedia provides a unique opportunity for educating students in digital literacy. We conclude with a summary of key findings, implications for researchers, and implications for the Wikipedia community.

    Abstract
    The large number and variety of online databases in the field of environment sciences and chemistry underlies the need for a cooperative evaluation approach. Presents 2 evaluation criteria, divided into 4 headings; general criteria (size of data source, cost of 1 hour searching, updating of database, availability on other media); chemical relevant criteria (number of chemicals, identification parameters of chemicals, test set chemicals, development of chemicals), environmental relevant criteria (information parameters for chemicals, parameter development); and criteria describing environmental chemicals (use of chemicals, quality of database). A 6 number scoring system is applied to these criteria and the Hasse diagram technique is presented for 19 bibliographic online databases using these criteria. Using this technique, 'good' and 'bad' databases are identified and changes in the database content from 1995 to 1998 can be visualized

    Abstract
    The key political and strategic issues which needs to be addressed for the future development of the Australian subject gateways are: continued quality of content creation, integration of access to print and electronic resources, archiving and persistent identification, sustainability of services and service integration. These issues will be more effectively tackled internationally, and the Australian subject gateways are keen to work with international collaborators to achieve a mutually beneficial outcome

    Abstract
    Reviews the current market for CD-ROM databases with particular reference to the online versus CD-ROM versus print debate. Concludes that the most likely scenario is a steady convergence of technologies, at least until the end of the century. Review the current and the most likely future developments in the area of CD-ROM database contents, software, hardware, and marketing. Concludes that users will choose databases on the basis of such factors as: ease of use; power of use; storage and delivery capacity; quality; functionaliy; timeliness; overall appeal; and real cost, not just price. Lists the most likely candidates for successful CD-ROM database development; not yet available. Concludes that Windows user faces will steadily replace DOS based systems, but not unless the Windows replacements are truly better and not just different. Recommends that both Windows and DOS interfaces be loaded onto the same CD-ROM with each database allowing the user to choose which to use. Reviews likely developments in CD-ROM hardware and marketing strategies

    Abstract
    Project SSG-FI at SUB Göttingen provides special subject gateways to international high quality Internet resources for scientific users. Internet sites are selected by subject specialists and described using an extension of qualified Dublin Core metadata. A basic evaluation is added. These descriptions are freely available and can be searched and browsed. These are now subject gateways for 3 subject ares: earth sciences (GeoGuide); mathematics (MathGuide); and Anglo-American culture (split into HistoryGuide and AnglistikGuide). Together they receive about 3.300 'hard' requests per day, thus reaching over 1 million requests per year. The project SSG-FI behind these guides is open to collaboration. Institutions and private persons wishing to contribute can notify the SSG-FI team or send full data sets. Regular contributors can request registration with the project to access the database via the Internet and create and edit records

    Abstract
    Contribution to an issue devoted on the weeding and maintenance of reference collections. CD-ROM has become part of the library universe and increasing numbers of libraries are considering the acquisition of reference tools in the new format. Issues of evaluation and selection, hardware purchase, and budget are primary concerns in this decision. Many aspects of day-to-day maintenance and access to CD-ROM sources must also be considered in the evaluation process. These issue-space, security, the care and feeding of hardware and software, reference assistance, staffing and staff training, and user instruction are vital to the success of CD-ROM in the library. Focuses particularly on literature about training for staff and users.

    Abstract
    'Quality-controlled subject gateways' are Internet services which apply a rich set of quality measures to support systematic resource discovery. Considerable manual effort is used to secure a selection of resources which meet quality criteria and to display a rich description of these resources with standards-based metadata. Regular checking and updating ensure good collection management. A main goal is to provide a high quality of subject access through indexing resources using controlled vocabularies and by offering a deep classification structure for advanced searching and browsing. This article provides an initial empirical overview of existing services of this kind, their approaches and technologies, based on proposed working definitions and typologies of subject gateways

    Abstract
    Telephone directories are one of the most used sources of information in a reference collection. As the library literature indicates, they are a stable reference tool with a strong history of use. Further, it has been observed that telephone directories are familiar to most users, and resources such as the community pages and yellow pages are used extensively. However, the emergence of CD-ROM technology and libraries being charged for printed directories has raised questions concerning the future of an all-print telephone directory collection in libraries. Yet, evaluation of acquisitions alternatives for these resources is largely missing in the library literature. In this article, Boettcher and Kingma review the literature regarding the use of telephone directories in academic and public libraries and provide a cost analysis of the four purchasing options regarding telephone directories: printed directories, directory assistance, Phonefiche, and CD-ROMs

    Abstract
    This study explores how and why people participate in collaborative knowledge-building practices in the context of Wikipedia. Based on a survey of 223 Wikipedians, this study examines the relationship between motivations, internal cognitive beliefs, social-relational factors, and knowledge-sharing intentions. Results from structural equation modeling (SEM) analysis reveal that attitudes, knowledge self-efficacy, and a basic norm of generalized reciprocity have significant and direct relationships with knowledge-sharing intentions. Altruism (an intrinsic motivator) is positively related to attitudes toward knowledge sharing, whereas reputation (an extrinsic motivator) is not a significant predictor of attitude. The study also reveals that a social-relational factor, namely, a sense of belonging, is related to knowledge-sharing intentions indirectly through different motivational and social factors such as altruism, subjective norms, knowledge self-efficacy, and generalized reciprocity. Implications for future research and practice are discussed.
